You will see better:
Think of the eye as a camera, and glasses as a new lens; the camera does not wear out because the lens was changed. We tend to think that glasses or contacts can make the eyes weaker and more dependant on them. In fact, the eyes do not "wear out" when the proper prescription lenses are used - you just see better! You may also have less strain and fewer tension headaches caused by squinting.

No:
For most eyeglasses provide improved vision and you will want to wear them to see better. For a few the eyeglasses provide corrections of things like eye misalignment in which case you will need to wear them. Not wearing the glasses for most cases simply prevents you from seeing clearly but does no harm to the eyes.

Better vision:
Spectacles, with proper prescription, correct the refractive error of your eyes. The benefits to wearing them is for clear vision. There is no downside to clear vision. Wear them when your vision requires the benefits of enhanced vision.

No:
This is a common misconception. Wearing glasses to correct refractive error does not make your vision worse or increase your refractive error over time. Refractive error is an imbalance between the length of your eye and it's optical power. Glasses simply compensate for that imbalance.

Unlikely:
If used for near sightedness or farsightedness or astigmatism, then if vision does improve, chances are it is unrelated to the glasses. Glasses help compensate for poor vision, but do not treat the underlying problems that lead to poor vision.

Like you can see:
For most people, there are no symptoms when wearing glasses for the first time (or changing glasses). A few people have a feeling of distortion or dizziness that usually goes away by continuing to wear the glasses for a few weeks. If you get nauseated or get a headache, then return to the place you got the glasses for evaluation.

11

No:
The eyes will not change for better or worse because you correct the vision with glasses. So not wearing them will have no effect except to force you to see things blurry all the time. Wearing them will clarify the vision but not alter the basic power.

Great!:
Most patients love their first pair of glasses since the new clarity of vision is remarkable. If the glasses correct astigmatism some may note the ground or floor feeling like it's tilting but this passes very quickly.

Night vision:
Most people see worse at night than by day. This is common for a few reasons. For one, many people are more near-sighted at night, since it is harder to pick a point of focus. Also, at night people rely more on the rods than the cones in their eyes, and rods are not as good at perceiving sharp details. If you cannot see at all during the night, this might indicate a true eye disease...

Depends:
This power can be worn all of the time, but many who need this slight correction wear glasses only to see better when conditions are not good, like driving in the rain or at night or attending a ball game (unless you have really good seats).

No:
Depends on the distance and font size. Presbyopes typically have loss of accommodation (variable amounts based on age), so they need extra help to focus on tiny things at near with reading glasses.
